Procedure Of Lymphadenectomy

1. Patients with penile cancer with inguinal lymph node enlargement should have inguinal lymph node biopsy during operation. 2. Patients with penile cancer who are pathologically confirmed to have inguinal lymph node metastases should undergo inguinal lymph node dissection (either at the same time as penile surgery or 2 to 3 weeks after penile surgery). 3.  Iliac and inguinal lymphadenectomy should be performed (either at the same time as penile surgery or 2 to 3 weeks after penile surgery) in patients with penile cancer that has metastases to "sentinel lymph nodes" located above and medial to the junction between the great saphenous and femoral veins. 1. Patients with heart, lung and other important organ dysfunction or poor systemic condition can not tolerate surgery. 2. Tumor with extensive metastasis. 1. Preoperative preparation Antibiotics should be used to prevent infection, and blood should be prepared for lymph node dissection. 2. The lymph node was biopsied 2 fingers away from the pubic tubercle and oblique incision was made to expose the fossa ovalis. Sentinel lymph nodes were found. All lymph nodes in this area were excised for pathological examination, and the incision was sutured after hemostasis. 3. Inguinal lymph node dissection can be performed by two sides of the inguinal arc incision, free flaps, removal of inguinal subcutaneous tissue, fascia and superficial and deep lymph nodes, indwelling drainage tube, and suture of the flap. 4. Iliac and inguinal lymph node dissection On the basis of inguinal lymph node dissection, the iliac vessels around the adipose lymphoid tissue, pelvic fascia, vascular sheath, etc.
